    <p>I've written a basic form library to mimic HTML forms in ActionScript, and everything was going well until Flash randomly decided my function call is no longer a function, but a property (or something along those lines.) I have an IFormElement interface, and HiddenElement implements it. When validating an element, FormManager calls clearValidationErrors() on that element, which is a function defined in the interface. When this happens on a HiddenElement, I get the following error:</p> <p>ReferenceError: Error #1069: Property dls.formmanager.form:IFormElement::clearValidationErrors not found on dls.formmanager.form.HiddenElement and there is no default value.</p> <p>The relevant code is copied below:</p> <p><strong>FormManager</strong></p> <pre><code>/** * helper function to check a single element's validity */ public function validateElement(element:IFormElement):Vector.&lt;IValidationError&gt; { Debug.out("Validating element " + element.name + " with value " + element.value + "...", Debug.DETAILS, _debugOptions); var errors:Vector.&lt;IValidationError&gt; = _formValidator.validateElement(element); element.clearValidationErrors(); if (errors.length &gt; 0) { watchElement(element); for each (var error:IValidationError in errors) { element.addValidationError(error); } } return errors; } </code></pre> <p><strong>IFormElement</strong></p> <pre><code>package dls.formmanager.form { import dls.formmanager.validator.errors.IValidationError; import org.osflash.signals.Signal; public interface IFormElement { function get name():String; function get value():*; function get valueChanged():Signal; function get validationRules():Object; function addValidationError(error:IValidationError):void; function removeValidationError(error:IValidationError):void; function clearValidationErrors():void; } } </code></pre> <p><strong>HiddenElement</strong></p> <pre><code>package dls.formmanager.form { import dls.debugger.Debug; import dls.formmanager.form.IFormElement; import dls.formmanager.validator.errors.IValidationError; import org.osflash.signals.Signal; /* * This class is used to represent non-interactable items in forms. */ public class HiddenElement implements IFormElement { ... /** * empty function, hidden element will never respond to removing errors */ public function clearValidationErrors():void { } } } </code></pre>

    1. COIs clearValidationErrors() called anywhere else in your program? Does the error you get include a line number and does this line number refer to the clearValidationErrors() call in validateElement()?

    2. COIs you whole project contained in a single swf file? It might be possible that you are including a swc which contains old definitions of HiddenElement and IFormElement.

    3. COI will have to check to see if clear validation errors is being called anywhere else, but it is definitely occurring in validate element. my project is currently made up of 3 swf files, all 3 of which I have recompiled with the newest version of the library Swc. I can confirm that the most recent library is being built and called because it is running debug statements correctly

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
